iPhone 7 iOS 13.2.3 Jailbreak
If your iPhone 7 or iPhone 7 Plus is currently jailbroken or you're interested in jailbreaking, you'll probably want to stay put on iOS 12.
Developers have released jailbreak tools that are compatible with iOS 12.4 and older versions of iOS 12. You can learn about them right here.
They've also released a jailbreak tool, dubbed checkra1n, that works with iOS 12.3-iOS 13.2.3 and iPhone 5s-iPhone X though the tool is currently in beta testing. It's unclear when it will leave beta.
